Aza can probably give you some figures on 'track day cats' - he's done the before & after dyno.
Its quite substantial from what I understand, 5 or 6 killerwasps.

my ''friend'' estimates the power gain to be around 5-7% after 5,000rpm but about the same level of bottom end power and a slight ''whirring'' noise, maybe he could have inserted a sleeve or somthing inside the cat so the flow wasnt all retarded an getting caught in the cat?? anyway he is happy with the result
